Specification of Letters Patent.

Patented Dec. 10, 1912.

Application filed April 18, 1910. Serial No. 556,163.

To all whom it may concern:

Be it known that I, WALTER FERRIS, a citizen of the United States, andresident of South Milwaukee, county of Milwaukee, and State oflVisconsin, have invented certain new and useful Improvements in RailwayPile-Drivers; and I do hereby declare the following to be a full, clear,and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to railway pile drivers, and it has specialreference to pile drivers of the locomotive type, that is to say, whichare propelled on the railway track by their own motive power.

The invention also relates to pile drivers wherein the leader frame andleaders are pivoted at the front of the car body on which the severalmechanisms of the pile driver are mounted, said leader frame and leadersbeing so arranged that they may be erected at different angles in orderto drive vertical. or batter piles, or folded back along the top of thepile driver in shipping position, wherein the leaders will liesubstantially within the lines of the machine and therefore permit thelatter to pass through tunnels and under bridges when the same is beingtransported from place to place in a freight train.

One object of the invention is to provide improved mechanism formounting and raising and lowering the leader frame and leaders, for thepurposes just described, and it is also aimed to furnish an improvedarrangement of the swinging deck or revolving frame, that carries theleaders and leader frame, with respect to the machine as a whole, and inparticular to the mechanism for swinging said deck or revolving frame ina lateral direction with respect to the car body, in order to drivepiles at the front of the latter and also at either side of the same.The mechanism to swing the deck is operated from anengine or enginesthat are fixedly mounted on the car body, at a point in the rear of theswinging deck, and said engine or engines are also used for erecting theleaders, driving the hoisting drums by means of which piles and the pilehammer are raised, and for propelling the pile driver from place to placI also aim to furnish improved means for swinging the leader carryingdeck and erecting the leaders through connections with a commonactuatingmechanism, which preferably comprises a drum rotatable on the car bodyand operatively connected with the leader frame, to raise and lower theleaders, said drum being driven from the engine or engines on the carbody and having mechanism associated therewith to lock it to theswinging deck or frame. When the drum is locked to said frame, therotation of the former will cause the latter to be swung horizontally,in which case the drum will have no raising or lowering action on theleaders carried by the deck owing to the fact that there is no relativemovement between the drum and deck; but when the drum is unlocked fromthe deck, the rotation of the former will produce the raising orlowering of the leaders. In order to hold the swinging deck stationarywhile the leaders are being raised and lowered, I employ in connectionwith said deck, a suitable brake, and said brake is preferably operatedautomatically from the means which looks the drum to the deck, to theend that as soon as said parts are unlocked, the brake will beautomatically applied to the deck to hold it fixed, whereas when thedrum and deck are coupled together again, the brake is automaticallymoved to its off position.

The novel features of the invention will appear clearly from thefollowing description and claims.

In the accompanying drawings, Figure 1 is a side elevation, partly inlongitudinal section, of a railway pile driver constructed in accordancewith the invention, the leaders being erected. Figs. 2 and 2 inconjunction, illustrate a portion of the pile driver in side elevationon an enlarged scale, Fig. 2 being drawn to a scale somewhat smallerthan Fig. 2, and a number of parts in Fig.2 being shown in verticalsection, with certain parts removed, Figs. 3 and 3 in conjunction,illustrate a portion of the pile driver in plan, Fig. 3 being partiallyin horizontal section, with certain parts broken away, Fig. 4 is anelevation of the front end of the machine, showing the leaders inclinedto drive piles having sidewise batter, Fig. 5 is a side elevationshowing portions of the swinging deck, leader frame, and leaders, theleaders and leader frame being in shipping position, Fig. 6 is atransverse section through certain parts illustrated in 1 two suitableropes wound on the leader rais- Fig. 5, and showing the rolling trucksby which a point on the leader frame is guided horizontally on the trackconstituted by the top chords of the swinging deck or frame, Fig. 7 is atop plan view of a portion of the swinging deck or frame and the rollerscarried thereby, Fig. 8 is a side elevation of the leader raising drumand its adjunctive parts, illustrating the mechanism for coupling anduncoupling the drum and swinging deck and automatically operating thebrake used in connection with said deck,"

Fig. 9 is a top plan view of the mechanism shown in Fig. 8, with certainparts removed, and Fig. 10 is a vertical central section illustrating ona larger scale certain parts shown 1 in Fig. 2.

In its general aspects, the pile driver illustrated in the drawingscomprises a car body A on which the several mechanisms are mounted, saidcar body traveling on the railway track by means of front and rearwheeled trucks B, G. Mounted on the rear ,part of the car is a steamboiler D which supplies steam to engines E that are preferably arrangednear the center of the car and at opposite sides thereof. Said enginesare connected by connecting rods (not shown) with a transverse crankshaft F, from which the usual hoisting drums G, H are driven by suitablegearing, as indicated in Fig. 3, said drums being adapted to hoist thepile hammer and to hoist piles, in the manner well understood in theart. The crank shaft F is also used to drive forwardly and rearwardlydirected inclined driving shafts I, J by means of which the front axle'of the rear truck C and the rear axle of the front truck B are drivenwhen it is desired to propel the machine by its own power or spot thesame with respect to the piles.

Mounted on the front end of the car body, for lateral swinging movementthereon, is a swinging deck or revolving frame K adapted to be swunghorizontally by means of a worm gear L (Fig. 2) driven from theinclined-driving shaft J by means of a-transmitting shaft M. Theworm:gear L is ar ranged to drive a leader raising drum N that is located atthe lower part of the deck and is adapted to be coupled to and uncoupledfrom the. latter by mechanism to be presently described. A leader frame0 is connected at one end, by means-of a pivoted radius rod I :to theforward lower end of the swinging deck, and connecting an intermediatepoint of said leader frame with 'a sliding cross head Q, that movesforward and rearward on the track formed by the top chords of theswinging deck, is a structural linker member R, pivoted to said crosshead and to said leader frame. The cross head Q has connected theretothe ends of ing drum N, in order that the cross head may be movedforward and rearward on its track and thereby raise and lower the leaderframe and leaders, as indicated in Figs. 1 and 5.

The leaders S are swiveled at T to the upper end of the leader frame(Fig. 2), as is usual in this class of machines, in order that theleaders may be inclined in a sidewise direction as indicated in Fig. 4,to drive piles with sidewise batter. The usual mechanism S is employedto give the leaders the desired slant, and any well known mechanism,such as that illustrated at S may be used to firmly lock the leaders inthe desired position. In the embodiment illustrated this mechanismcomprises a curved track .9 on the leader frame, on which track a curvedpiece .9 connecting the leaders is arranged to slide, a small pin 8being adapted to engage registering perforations in the members s, s,and thereby lock the leaders in place. The particular construction ofthe leaders and leader frame and their adjunctive parts is entirelyimmaterial to the purposes of the present invention.

Turning now to the detailed construction of the machine, it will beobserved from Fig. 3 that the transverse operating shaft F is providedat its intermediate portion, beneath the hoisting drums, with alongitudinally slidable sleeve or quill 25 to the ends of which beveledgears 26, 27 are secured, the gear 26 being smaller than the gear 27,Although the sleeve 25 is slidable along the operating shaft it issuitably keyed thereon in order that it may be rotated by the rotationof said shaft. Coacting with the smaller gear 26 are similar bevel gears28 fixed at the upper ends of the driving shafts I, J, respectively, theupper ends of said shafts being suitably journaled in fixed bearings onthe car body, and the lower ends being in operative connection withaxles of the front and rear trucks, preferably as set forth in mydivisional application Serial No. 625,863, filed May 8, 1911. Adjacentthe end gears .28 on the driving shafts are similar gears 29 which areof about the same size as said gears 28 in the embodiment shown and aredesigned to coact with the larger sleeve gear 27. The sleeve 25 isprovided at one end with a'oollar 30 that is secured to a pivoted forked.rod 31, to which motion is transmitted by means of a rod 32 inconnection with an appropriate lever (not shown), so that the sleeve 25may be slid lengthwise on the operating shaft in order to engage itssmall gear 26 with the gears 28 of the driving shafts, in which case thedriving shafts will be driven at a comparatively slow speed, or so thatthe larger gear 27 at the opposite end of said sleeve may be engagedwith the gears 29 on the respective driving shafts, with the re sultthat a much faster speed will be imparted to said shafts. The fast speedis used when it is necessary to propel the pile driver from place toplace under its own,

motive power, while the slow speed is used in accurately spotting themachine with respect to the piles to be operated upon. It is evidentthat by suitably manipulating the lever connect-ions 323l, which aremerely indicated by way of example, the sleeve 25 may be shifted to anintermediate position wherein its gears will not engage any of the gearson the driving shafts, so that the rotation of the main shaft F willhave no effect on the driving shafts. Fig. 3 illustrates clearly thecranks f on the ends of the shaft F, and the positions of the connectingrods, which are omitted in this view, are indicated by the dotted lines7".

The leader raising drum N is actuated from the forward driving shaft J,and this is effected through the following connectins :Said shaft J haskeyed thereon, intermediate of its ends, a small bevel pinion 33 withwhich engages a large bevel gear 34 loosely mounted on the rear end ofthe transmitting shaft M and adapted to be locked thereto by a suitableclutch 34 operated by a suitable lever 34 Fig. 3. The transmitting shaftM is journaled horizontally in bearings in the car body and carries atits forward end a worm 35 that meshes with the large worm wheel L, itbeing evident from Fig. 3 that the shaft M is ar ranged at an angle tothe center line of the car and is directed tangentially to the largeworm wheel. The transmitting shaft is illustrated as made up of twosections, which are detachably coupled together by means of a couplingdevice 36 of any approved form, whereby the worm wheel L may beuncoupled from the driving shaft J if such is desired.

The worm wheel L, which is located in a horizontal plane andapproximately in line with the car bottom or deck, beneath the swingingdeck or revolving frame K, is journaled in the car body by means of acomparatively long upwardly extending hub 37, to which it is bolted,said hub being freely movable in a bearing 38 formed at the center of aspider 39 applied to the deck of the car body. The spider 39 serves tojournal the worm wheel, leader raising drum and swinging deck on the carbody, and it is preferably made circular in shape, presenting at itsperipheral portion a raised circular track 40 on which travel rollers 41journaled between pairs of cross beams 42 that connect the lower sidemembers 43 of the swinging deck. Two rollers 41 are preferably used inconnect-ion with each pair of cross beams, so that the swinging deckwill be supported on the track 40 at four points, arranged in arectangle, as indicated in Fig. 3. In this way, the swinging decktogether with the load imposed thereon by the leader frame and leaders,is effectively sustained, and its movement in a horizontal plane isconsiderably facilitated. As shown in Fig. 2, the upper outer surface ofthe bearing 38 of the deck casting is made smooth and cylindrical inorder to serve as a bearing for a casting or bearing member 4-4 that isfixed between the lower side members of the swinging deck, in the centerline of the latter, and fits over the cylindrical part of the fixedbearing 38. The central casting 44 of the deck is provided with alaterally directed web in which a circular series of perforations 45 ispierced, asshown in Figs. 9 and 10, said perforations or holes beingarranged in pairs of which the individual holes are diametricallydirected with respect to the hollow hub of the worm wheel, with Whichhub the said'series of openings is concentric. These holes in the centercasting of the swinging deck are designed to be engaged by dependingpins 46 carried by a vertically movable driving collar 47 normallyresting on the upper surface of the drum N, as best shown in Fig. 10,said pins, which are fixed to the driving collar 47 being extendeddownward through openings in the web of the drum. The drum is drivenfrom the worm wheel L by means of a key 37- associated with the hub 37,and the driving collar 47 for the deck is in turn driven by the drum bymeans of the pins 46. The collar may be lifted slightly to disengagesaid pins from the deck casting, by means of a ring or collar 48, butthis movement will not be sufficient to disengage the pins from theholes in the drum. The operating ring 48 for the driving collar isactuated in the manner to be hereinafter described.

As previously intimated, the leaders are raised and lowered by means ofa single rope wound on the drum N, and in the drawings these ropes aredesignated by reference character 49. The end portions of said ropeswhich extend forward and rearward respectively with respect to theswinging deck, pass over suitable sheaves 50, 51 carried by the swingingdeck at its front and rear ends respectively, said sheaves beingjournaled in any convenient way at points in the center line of the deckand being located between the top chords of said deck. The upper chordsof the deck, which are connected with the lower chords by suitableinclined braces, as shown, serve as a track on which the cross head Q,is guided in for- Ward and rearward direction, said cross head beingpreferably constituted by an I-beam to the opposite flanges of which theends of the ropes 49 are connected, as shown at 52 and 53 in Fig. 3 Thecross head Q,

is pivoted at 54, 55 to the structural link R previously referred to,the pivots 5455 being located at the corners of said link or member,which comprises suitably braced longitudinally extending side members,as shown. At the forward corners of the link or member R the same ispivoted to the leader frame 0, intermediate of the ends of said frame,as indicated at 56 and 57.

At a point in advance of the pivots 56 and 57, the leader frame isprovided with a transverse rock shaft 58'wliich is mounted at the endsin small rolling trucks 59 that move forward and rearward on the topchords of the swinging deck. This arrangement is illustrated in Figs. 5and 6 from which it appears that each rolling truck 59 is hollowed outto providean interior chamher in which rollers 60 are journaled atopposite sides of the rock shaft 58, said rollers traveling on members61 applied to the upper chords of the swinging deck, as indicated. Eachtruck 59 is provided with a base flange 62 provided with a perforationto receive a locking pin 63 adapted to extend into perforations 64arranged longitudinally at different points in the length of the topchords, whereby the trucks and leader frame may be locked in the desiredposition. In Fig. 2 the leaders are shown erected, and. it appears thatwhen the parts are in this position the trucks are at the extremeforward ends of the chords of the swinging deck, in which position thepins 63 lock them in :place, as described. l/Vhen the leaders are in theperpendicular position shown, vertical piles can be driven, but if it isdesired to drive batter piles, the leaders will not be forced into theirvertical position, but will take an intermediate position, in which thepins 63 are engaged with corresponding perforations of the longitudinalseries, as will be understood. The sliding pivotal connec tion of theleader frame with the upper portion of the deck, by means such astheshaft 58 and the trucks 59, orequivalent means, is one of the importantfeatures of the invention, inasmuch as it sustains the leader frameeffectively in all of its various positions- The ease with which theleader frame may be raised and lowered is also very much increased byguiding along the longitudinal track or guideway of the deck, a devicesecured to the leader frame at an intermediate point in the length ofthe latter but having apivotal movement with respect to said frame. Theropes on the hoisting drums are led downward through the car body andover suitable sheaves 65 located beneath the hub 37 ofthe worm wheel,and

said ropes are led up through said hub over sheaves66 journaled in theupper portion ofthe swinging deck, and then pass under the sheaves67carried at the extremityof the leader frameO, as shown in Fig. 1. Whenthe leader frame and leaders are erected, therefore, the raising of thepile hammer and of individual piles by means of the ropes referred tocan be easily effected.

When the machine is properly located and it is desired to drive piles ateither side of the same, the driving shafts I and J are un coupled fromthe driving wheels, and the shaft J is coupled to the transmitting shaftM by means of the clutch 34. The shaftJ is then rotated by the primemover at the low speed and in such a direction as to swing the deck intothe desired position by means of the connections previously described.At this time, the pins 46 of the driving collar 47 are engaged with theperforations 45 in the center casting of the swinging deck, as shown inFig. 10, and accordingly the rotation of the hollow hub 37 of the wormwheel will produce the rotation of the swinging deck as a whole, as wellas the rotation of the leader raising drum N, and as the drum and deckhave no relative turning movement there will be no raising of theleaders. After the swinging deck has reached its ultimate position, theleaders are raised by giving the collar 48 on the driving flange 47 avertical movement, which will pull the pins 46 out of the perforationsin the center casting of the swinging deck so that the drum N canrevolve independently of said deck. During the rotation of the drum, thedeck is held stationary in its adjusted position by means of a bandbrake 68 that is brought into tight contact with a circular brakesurface 69 mounted on the deck of the car, the brake band 68 beingcarried by the swinging deck structure, as shown in Fig. 8.

In order to effect the raising and lowering of the collar 48 andtherefore of the driving flange 47, and its pins 46, and to produce theautomatic actuation of the brake (38, 69 the following mechanism isprovided :A hand lever 70 (Fig. 8) is connected by means of a reach rod71 and bell crank 72 to rock shaft 72 by means of which motion istransmitted through a crank 72*, to a hollow reach rod 73 which extendsup through the hub 37 of the worm wheel in the axis of rotation. Thereach rod 73 may conveniently be formed of a section of pipe, and itdoes not rotate with the swinging deck, but is provided at its upper endwith a collar 74 that is threaded thereon. The collar 74 can thereforeswing laterally with the swinging deck or revolving frame K but remainsin engagement with the pipe 43 at all times. Pivoted to the collar 74 isa bell crank 75 mounted on a shaft 76 that supports parallel arms 77,the ends of which have a slotted connection 78 with the raising andlowering collar 48, as indicated in Figs. 8 and 9. Acting on the rockshaft 76 is a counterweight 79, by means of which the raising of thedriving flange 47 is facilitated, as will be understood. The upper endof the bell crank or elbow lever is pivotally connected at with a reachrod 81 pivoted to a crank 82 on an upright shaft 83 journaled in theupper and lower frame members of the swinging deck. At its lower end theshaft 83, which is rocked through its connection with the reach rod 81and elbow lever 7 5, carries pins 84 connected in the usual way with thebrake band 68. It will therefore be understood that when the drivingcollar 47 is unlocked from the swinging deck casting, by suitablymanipulating the lever 70 and thereby raising the collar 48, theresulting rocking movement of the upright shaft 83 will cause thefrictional engagement of the brake band 68 with the coacting frictionsurface provided on the car, with respect to which surface the brakeband is, of course, movable angularly when said band is loose. Anopposite movement of the operating lever 70 will, of course, effect thelowering of the driving flange 47 into locking engagement with thecenter casting of the swinging deck, so that the drum N and said deckwill be locked together again, and this will produce an automaticrelease of the brake 68, 69, by a reversal of the operations previouslydescribed. In this way, provision is made for automatically locking theswinging deck in its adjusted position by the means to uncouple theswinging deck and drum from each other, whereby the locking of the deckin position is produced directly by the devices that are brought intoplay as a preliminary to the raising of the leaders. It might be statedat this point that the friction surface 69 alluded to may beconveniently formed by the outer surface or periphery of the main fixeddeck casting or spider 39, provided with the circumferential track 40 onwhich the swinging deck rolls by means of the rollers previouslydescribed. The several pairs of holes 45 in the deck center castingpermit connection of the swinging mechanism to the leaders in variouspositionsone pair of holes is engaged by the pins 46 when the leadersare down,

another pair when the leaders are up, and several other pairs when theleaders have different degrees of backward slopeto provide for thedriving of slanting or batter piles, that is to say, piles batteredlongitudinally of the swinging deck. The provisions for giving the pilesa sidewise batter have already been described.

Of course the transmitting shaft M from which the swinging deck andleaders are operated must not be driven when the machine is beingpropelled. The clutch 34 is therefore actuated to uncouple the shafts Jand M. Obviously, the gear 34 will rotate idly on the transmitting shaftwhen the machineis being propelled and it is not de sired to raise orlower the leaders or effect the swinging of the deck.

IVhen the machine is to be driven at a comparatively slow speed, inorder to spot the machine with respect to the piles or to enable it tohaul heavy loads up grades, the quill or sleeve 25 is moved into such aposition that the smaller gear 26 thereon will be brought intooperation, as will be understood. After the machine has been properlylocated, and it is desired to swing the deck or raise the leaders, theaxle connections at the lower ends of the driving shafts are uncoupledfrom the trucks, and the transmitting shaft M is then coupled to thegear 34, as above indicated, in order that the rotation of the drivingshaft J, at either of two speeds, may produce the rotation of thetransmitting shaft and the operation of the swinging deck and leaders.When, during the operation on the piles, it becomes necessary to movethe machine again, this is produced by unclutching thegear 34, so thatit will rotate idly, and then clutching in the connections on thedriving shafts and driving car axles respectively.

It is to be understood that I have not attempted to describe all of themodifications of the construction that may be adopted without departingfrom the invention. Among the most obvious modifications is thereplacement of the sliding cross head of the leader raising and loweringmechanism by difierent means topush up and lower the leader frame, andthe substitution for the worm gear of the swinging deck, of an operatingmember of another type.
